Major overhaul of changelog retrieval

[viceice]

What would you like Renovate to be able to do?

We should do a major refactoring of the current changelog retrieval to support more datasources. Currently we only support GitLab and GitHub.

If you have any ideas on how this should be implemented, please tell us here.

Refactor existing code to decouple gitlab and github code. Use base classes for shared code / functions.

Is this a feature you are interested in implementing yourself?

Maybe

@viceice There's a typo in the issue title.

retrival should be spelled retrieval.

Or you can replace retrieval with fetching to use a simpler word.

You can keep it 😝

Would you consider support for running a script in the host repo to fetch release notes for "known" things that renovate doesn't necessarily need to implement itself?

no

What if there's release notes available on GitHub, but no CHANGELOG file in the repo/package (i.e. the release notes are not apart of the repo's contents/git objects)? Will renovate still pull release notes from the descriptions of GitHub releases?

It would be great to be able to configure custom URLs for release notes sources where renovate could fetch it's info from.

e.g. For all Android Jetpack releases notes, renovate is currently unable to get the notes since Google publish all their releasenotest on https://developer.android.com/jetpack/androidx/versions

Is this the issue to track for Ruby changelogs as well?

i think that should be a separate feature but can be tracked in list of this issue. please create a feature discussion to describe what the expected behavior should be.

I would like to templatize custom changelog URLs (customFullChangelogUrlTemplate?) to use something like : https://gitlab.com/myorg/myproject/-/releases/scope-1%2Fcomponent-1%2F{{{version}}}

Context: we have a "monorepo" with independent release object for each component (here docker images), we choose to name releases with something like scope-1/component-1/v1.2.3 (gitlab replaces / with %2F in URLs).

Another way to match our needs will be to specify a release name prefix (by example: scope-1%2Fcomponent-1%2F).

@rarkins FYI, this is the situation for our private packages. We have no CHANGELOG.md file, but we have the releases on Github.
